Amprobe’s AMP-330 True-RMS Clamp Meter offers a complete range of measuring functions for modern industrial environments, motor testing and HVAC applications. The AMP-330 features True-RMS sensing, low pass filters and fast response processors for quick, error-free measurements. The Amp-Tip function allows for precise measurement of current down to the tenth of an Amp, and a third input jack enables motor rotation and 3-phase sequence testing. GET ACCURATE MEASUREMENTS: The Amprobe AMP-330 provides accurate measurement of current, voltage and frequency on all electrical systems including distorted, non-sinusoidal signals (True-RMS function) and variable frequency drives (low-pass filter). 3-PHASE MOTOR AND PHASE ROTATION: Tests allow proper connection of a motor to a 3-phase system. Improperly connected motors will spin in a reverse direction, which may destroy the motor or equipment connected to it. INDUSTRIAL MOTOR MAINTENANCE: Inrush current measurement for motor start-up monitoring allows users to verify that the motor is receiving the required inrush current to support proper motor start.
